Can someone please share the idea how to use Fenwick Tree in True Game

Basically what you can do is maintain pairs (height[i],i) and sort them by heights, and now maintain a BIT Tree over N elements of the array, where ith index of the BIT Tree denotes the ith index of the original array.
Now for every index 1<=i<=N, in pairs(described above), update the BIT array at index pair[i].second with value pair[i].first and dp[i] = Prefix sum of the elements of the BIT Tree from 1 to pair[i].second.

The answer will be the max(dp[i]) , 1<=i<=N.
